Derby ware, porcelain figures and service wares made in Derby, central England, about 1750–1848. The best-known early figures were characterized by glaze retractions about the base. Known as “dry-edge” figures, their modeling and execution were excellent, the porcelain soft and heavy; a pair known as the “Florentine Boars,” after Italian bronzes, is the most noted example. The modern Royal Crown Derby factory dates from 1875[1].

In the short story “The Mission of Jane” Crown Derby is mentioned as the heirloom Alice Lethbury inherited from her family. In the opinion of Mr. Lethbury, his wife inherited not only the porcelain, but also the set of everyday philosophies, which leads Mr. Lethbury to the conclusion, his wife cannot build her own opinion.
